The Short Answer
An Intermodal Marketing Company (IMC) is a company that holds direct contracts with Class I railroads and sells intermodal transportation services to shippers and 3PL partners. IMCs coordinate the full door-to-door move — origin drayage, rail transit, and destination drayage — under one roof, with one point of contact, using railroad-direct capacity and pricing.
The term "IMC" is a federally recognized designation. IMCs are registered with and regulated by the Surface Transportation Board (STB) — the federal agency that oversees railroad transportation in the United States.
An IMC is the company that sits between the railroad and the shipper — holding direct railroad contracts, managing the full move, and selling intermodal capacity as a complete door-to-door service.
What IMCs Actually Do
When a shipper wants to move freight by intermodal rail, they have a problem: the railroad doesn't manage trucks. The railroad moves containers from ramp to ramp — but getting the container to and from those ramps requires local drayage carriers at each end. Coordinating all of this requires specialized knowledge, established relationships, and direct access to railroad capacity.
That's what an IMC does. A full-service IMC handles:
- Origin drayage — arranging the local truck that picks up the container and brings it to the rail ramp
- Railroad booking — securing capacity on the right train through direct railroad contracts
- Rail transit — managing the container from origin ramp to destination ramp
- Destination drayage — arranging the local truck that picks up the container at the destination ramp and delivers it to the consignee
- Documentation and tracking — managing all paperwork and providing real-time visibility throughout the move
- Single invoice — billing the complete door-to-door move as one transaction
IMC vs. Freight Broker — The Critical Difference
This is the most important distinction in intermodal freight — and the one most shippers don't understand until it costs them money. On the surface, an IMC and a freight broker offering intermodal can look identical. They both quote rates. They both arrange moves. They're often described the same way. But the structural difference is enormous.
A direct IMC holds railroad contracts. A freight broker does not. When a broker offers intermodal, they're purchasing capacity from an IMC and marking it up before passing it to you. That markup appears on your freight bill every single load — whether or not anyone tells you it's there.
Here's what that looks like in practice on a real lane:
| Factor | Direct IMC | Broker Offering Intermodal |
|---|---|---|
| Railroad contracts | Direct with Class I Railroads | None — buys from an IMC |
| Rate you receive | Railroad-direct pricing | Railroad rate + IMC margin + broker margin |
| Margin layers | One — the IMC's margin | Two — IMC margin + broker margin |
| Capacity in tight markets | Contracted allocation holds | Gets what's left after IMC fills contracts |
| Drayage relationships | Built directly at each ramp | Inherited through the IMC they buy from |
| Problem resolution | Direct access to railroad | Calls the IMC, who calls the railroad |
| Surface Transportation Board | Federally registered IMC | Registered as broker, not IMC |
The dollar impact of those extra margin layers is real. On a $2,500 intermodal load, a broker adding 10–15% adds $250–$375 per load. At 20 loads per month that's $5,000–$7,500 per month — $60,000–$90,000 per year paid for a layer of service that adds no value to your freight move.
How Many IMCs Are There?
There are hundreds of companies that call themselves intermodal providers — but very few are true direct IMCs with contracts across all Class I railroads. LaserNet Jax is a direct IMC in the United States with direct contracts with CSX, Norfolk Southern, Union Pacific, CN Rail, and CP Rail — plus access to BNSF-served lanes through established carrier relationships — plus access to BNSF-served lanes through established carrier relationships — CSX Transportation, Norfolk Southern, Union Pacific, CN Rail, and CP Rail.
Having direct contracts with CSX, Norfolk Southern, Union Pacific, CN Rail, and CP Rail — plus access to BNSF-served lanes through established carrier relationships — plus access to BNSF-served lanes through established carrier relationships means full North American coverage — every major lane, every major market, with railroad-direct pricing across the entire network. A provider with contracts on only one or two railroads has significant geographic blind spots and can't offer true competitive pricing across all lanes.
The Six Class I Railroads
Understanding which railroads serve which parts of the country helps explain why full Class I coverage matters:
- Union Pacific — Western US primary carrier, major transcontinental lanes, strong Pacific Northwest and Midwest service
- CSX Transportation — Eastern US primary carrier, Southeast to Midwest and Northeast lanes, Florida to Chicago corridor
- Norfolk Southern — Eastern US, strong Southeast and Mid-Atlantic service, Atlanta and Charlotte hubs
- Union Pacific — Western US, Southwest lanes, LA to Midwest transcontinental service
- CN Rail — Canada's largest railroad, US–Canada cross-border service, Eastern Canada to US Midwest
- CP Rail — Western Canada primary carrier, Vancouver BC to US Midwest, cross-border to Chicago
A shipper moving freight from Jacksonville to Los Angeles needs Union Pacific access for the western portion of that move. A provider without those contracts can't give you a true direct rate on that lane — they're buying it from someone who does. Every lane you run with a provider who lacks direct contracts on that railroad is a lane where you're paying an extra margin layer.
What to Ask Before Choosing an Intermodal Provider
The single most important question you can ask any intermodal provider is simple: "Do you hold direct contracts with the Class I Railroads, and which ones?"
A direct IMC will answer immediately and name the specific railroads. A broker will use vague language — "we have strong railroad relationships" or "we work closely with all the major carriers" — without ever saying the words "direct contract." That distinction tells you everything about the rates you'll receive and the capacity you'll have access to.
